Liquid processing method making use of pipette device and apparatus for same

A liquid processing apparatus using a pipette device, said liquid processing apparatus comprising a liquid sucking/discharging line which can move in the horizontal direction and in the vertical direction;

• a means for performing liquid sucking/discharging steps through said liquid sucking/discharging line;
• a plurality of hollow cylinders required for processing one type of liquid and provided along the horizontal direction in which the liquid sucking/discharging line moves;
• a magnet configured for attracting magnetic particles contained in a liquid onto an internal surface of each of said plurality of hollow cylinders when the liquid is sucked into or discharged from said cylinders;
• a vessel for containing said liquid therein;
• one or more filter holders each having a filter required for the desired processing;
• and one or more vessels for containing other types of liquid therein required for the processing, and means for driving and controlling the liquid sucking/discharging line or a cylinder positioned therein according to instructions from a control unit so that the line or the cylinder is transferred with a filter holder positioned therein to perform at least one step selected from quantifying, separating, taking out, pipetting, clarifying, condensing, and diluting the liquid or a target high molecular substance contained in the liquid.

• a means for performing liquid sucking/discharging steps through said liquid sucking/discharging line;
• a plurality of hollow cylinders required for processing one type of liquid and provided along the horizontal direction in which the liquid sucking/discharging line moves;
• at least one type of filter positioned in one of said plurality of hollow cylinders;
• a vessel for containing said liquid therein;
• a magnet configured for creating an external magnetic field for attracting magnetic particles contained in a liquid onto an internal surface of a cylinder when the liquid is sucked into or discharged from said cylinder;
• and one or more vessels for containing other types of liquid accommodated therein required for the processing, and means for driving and controlling the liquid sucking/discharginig line or a cylinder positioned therein according to instructions from a control unit so that the cylinder is transferred to perform at least one step selected from capturing, extracting, isolating, amplifying, labelling, and measuring a liquid or a target high molecular substance contained in the liquid.
